新型厚膜包衣对油菜种子发芽与苗期生长的影响

甘蓝型油菜、白菜型油菜杂交种子经厚膜包衣后，种子重量可增加15％～50％，体积增大0．5～1．0倍，种子发芽率、发芽势和发芽指数均可提高，其中，厚膜包衣甘蓝型油菜成油1号和陕油9号杂种的发芽指数与对照相比差异达显著水平，白菜型油菜白杂1号种子差异不显著。厚膜包衣后显著促进了油菜杂交种子根系的生长。包衣种子贮藏6个月后发芽状况良好，种子的成苗数最大叶长宽、苗高、叶片数、鲜叶、鲜根与干叶、干根重均高于对照。

Effects of a Novel Encrustation on Germination and Seedling Growth of Oilseed Rape

weight by 15%~50% and the seed volume by 0.5~1.0,and improve the germination percentage,germination vigor and germination index of the seeds,in which the germination index of encrusted Chengyou No.1 and Shaanyou No.8 was very significantly different from the check''s and the germination index of encrusted Baiza No.1 was significantly different from the check''s. The encrustation significantly promoted the root growth of oilseed rape. The encrusted seeds stored for 6 months germinated well. The establishment of seedlings,the maximum leaf length and width,the plant height,the number of leaves,and the fresh and dried plant weight of encrusted seeds of oilseed rape were all greater than those of check''s.
